To all whom 'it may concern: f

Be it known that I, IVVLLIAM jVOGEL, of Chicago, in the 4county of Cook and State of Illinois, have invented certain new and useful-Improvements'in Car-Heating Devices; and I do hereby declare that the'following is a full, clear, and exact description thereof, refv erence being had to the accompanying drawings, aud to the letters of reference marked 1o thereomwhich form a part of this specifica?l tion.

This invention embraces a novel construction in devices for heating street-cars, wherein certain novel features of construction in I5 van oil-burning apparatus set forth in a prior application for patent, Serial No. 210,046, iiled August 5, 1886, are applied for the purpose mentioned, and other features of construction in car-heating devices, as hereinafter A'fully zo explained, and pointed out in the appended claims. In the said prior application a novel hea-ting device is described and shown, comprising in its essential featuresa` nre-box Sustaining a perforate bed, means supplying oil to y 2 5 said bed, anda plate or casting provided with a depending part or iiange extending downwardly into the hre-box near the side walls of thelatter and fo-rm-ingwithithe said side Walls and other parts of theabu-rner a passage 3o delivering-air for maintaining combustion to a point near the surface'ofrthesaid perforate bed. i

The heating device herein illustrated comiprises la burner made asabove described,

which is inclosed by a iiat or lowcasing or housing located in thebottom of the car, with Its top surface slightly below orupon a level with the car-Hoon a protecting pl'ate or grat' line a: x of Fig. 2. view of the'heating device, portions of the connection with the accompanying drawings,

,fully illustrating my invention.

5 is a longitudinal verticaljsection of the same, taken upon line .fr of Fig. 4. Fig. 6 65 =is a transverse sectional View taken upon line a: fFig. 5.- Fig. 7 is a detail plan View of devices upon the car for controlling the outlet-openings of the smoke-pipes. In the said drawings, A indicates the car- 7c body, B the heating device as a whole, and C- an oil-tank from which the heating device is supplied through a pipe D.

As herein shown, the heating device is made generally hat; in form or with little height in proportion toits width and length, andsaid heating device is located at the mid- 'die of the car-noon Vllhe tank C is shown as placedV beneath oneOf y. the seats at one end of the car. As farasethe general purposes of -So the invention are concerned, the heating device'when'tlrus `located may be sustained in any suitable manner by the iioor or framing A thereof; but in the particular construction illustrated the flat casing ofthe heating device rests upon the iioor A which is commonly present in cars, and a raised secondary floor or grating A2 is placed upon the said floor A with its top surface at or near the level of the top surface of the heating device, said raised 9o part or floor forming a Shallow recess or pit in which the heating device is placed. This j construction will generally be used in placing the heating device in cars already built; but

in cars especially constructed to receive the 9 5 heating device the latter will preferably be located in a space or depression formed for the purpose in the floor-frame-of the car.

I n cases in which it is vdesired to remove the heating apparatus from the car in sum- Ica mer the secondary iioor or grating will consist of` two removable pieces located one at each end of the heating device, as seen in Fig. 4, so that the said heating device and both gratings may be taken out and replaced by a single grating, which may or may not be as high as the gratings employed with the heating device.

The heating device proper, consisting of the oil-burner and its casing or housing, is, as

-tended beyond the walls g' of the box G, so

herein shown, constructed as follows:

E indicates the outer casing or housing of the heating device, being shown as made with a lower trough-shaped part E', having a flat bottom and low vertical sidewalls,.andwith' a top E2, highest in the middle and sloping outwardly and downwardly to `the several sides of the casing. Said casing is desirably provided with short legs or projections e upon its lower surface, by which it is sustained upon ahorizontal plate 0I grating F, which is also provided with short legs ff, resting upon the car-Hoor, a metal plate Fbeing desirably interposed between said plate F and the Hoor to more fully protect the latter from the heat of the casing. The side and top walls of the casing E are preferably corrugated, as shown, to increase the eective heating surface of the device.

G is a shallow box, which forms part of the casing, of the burner proper and which is preferably made of cast metal with a flat bottom gand vertical walls g.V Said box G rests within the casingE upon the bottom of the latter, and is herein shown as made hexagonal in .plan view; but this shape thereof is not essential. Upon the flat bottom of the said boxy G, within the outer walls g thereof, is cast an upwardly-extending iiange or wall G', herein shown as rectangular in plan, and which forms a shallow receptacle or trough in the central part of the box G.

II is a rectangular frame without bottom or top, which is sustained. upon the bott-om of the box G within the flange or wall G', with its bottom edges elevated slightly above the said bottom, a space 71, being provided betweenrthe wall G and thesaid frame H, so as to afford a passage between the said frame and the adjacent parts of the box G. The said` frame II is, as shown, sustained in the position described by means of lugs or projections h h upon its lower edge.

I is aperforated bed, preferably of asbestus, iirebrick, orv similar porous material, but which may be of perforated cast-iron. Said bed 'fills the open bottoni of the frame H and is preferably supported upon studs or projections g2 upon the surface of the bottom g of the said box J is a top plate or casting, which rests upon the upper edgeV of the box G and closes the top of said box,4with thee-xception of a centralV exit-opening j, located over the porous bed I, said casting being provided with a depending iiange J', extending downwardly within the frame ll, near the side walls thereof, and surrounding the opening j. Said flange terminates at its lower` edge slightly above the top surface of the perforate bed I, andthe top edge of ,the said frame I-I is terminated at a short distance below the under surface of the top plate J, thereby forming a passage j', leading from the space of theburner wit-hin the .box G, exterior to the frame I, between said frame andthe flange J', to the top of the bed I. The said top plate J is exasto form partitions to cause a circulation of air within the casing E, as will be hereinafter described.

' The oil-'supply pipe D, which extends from the tank C beneath the car-floor to the burner, is extended upwardly through the plate F and the casing E and is fixed in the bottom g of the box G within the wall or flange G', so as to deliver the oil into the trough or receptacle formed by said wall G' beneath the bed I, through which the oil rises in the operation of the burner, as will hereinafter more fully appear. The top of the said wall G is preferably lower than the loweredge of the'flange J', so thatv the oil which rises through the porous bed H may overflow the wall G' into the part of the boxV G exterior to said wall, and thereby prevent the closing of the air-passage between the top of the bed and the said. Iiange.

K K are air-supply tubes, which extend from points beneath the car upwardly through the casing E and box G, and which open Within the latter. Said tubes K K are preferably extended upwardly through the box G to points near the top of the latter, and are desirably provided at their lower ends with open-ended cross-tubes K K', arranged horizontally and parallel with the sides o'f the car, whereby the influx of air to the tubes will be facilitated when the car is moving in either direction, said tubes K' K' being preferably made' bell-mouthed, asshown, to favor the influx of air thereto.

The top plate J ofthe burner is extended beyond the walls.` of the box G and in such manner as to come in contact with the verti- IOC IIO

cal walls of the casing at the longer sides at each side of the burner and are fixed at their upper ends in the top plate J, so as to communicate with the space above said plate, and extend downwardly through the bottom of the casingE and the car-floor andare provided with suitable exit-openings, a particuw 416,877 i a lar, construct-ion of which is herein shown and will be hereinafter described; The pipes M are herein shown as located upon a transverse line passing throughthe center of the burner, and the partition J 2 is shown as made with oifsets j2 j? at its ends, extending between the burner-outletj and the said pipes,'so `that the direct passage of the products of combustion from the said outlet j to the exitpipes is prevented.

In the operation of the heating devicethe oil admitted through the pipe D rises through the perforate bed I and is burned in thespace or combustion-chamber above the bed. The air entering the box G through the air-pi pes K K passes downwardly throughV the space j between the frame H and ilange J and is thereby delivered at a point adjacent to the top of the bed-I, where-combustion takes place. Any surplus oil passing over the wall G to thebox G is therein vaporized and passes to the combustion-chamber with the air from the tubes K K and is there burned. The flames and products of combustion. pass upwardly through the aperture j in the top plate J and are carried toward one end of the casing over said topl plate, as indicated by the arrows in the drawings, the transverse partition J 2 preventing the passage thereof in the contrarydirection. Upon reaching the end of the casing the said products of combustion pass downwardlywaround the edge of the` plate J and then backwardly beneath said plate and around the sides of the box G to the opposite end of the casing.-

At this point they pass upwardly around the edgeof the plate J and they then pass over said plate toward the middle of the casing,'where vthey encounter the partition J 2 and are carried downwardly'and out of the casing through the pipes M M, Bythis construction a' circulation of the dames and heated products of combustion from the burner is obviously maintained throughout all' parts'of theicasing of the heating device. i The cold-air-inlet pipes K K* are made much smaller in crosssectional area than the exit-pipes -M M, thereby insuring -the outward passage from the burner of theheated products of combustion and the necessary draft through the burner. To allow access to the burner for lighting it and for other purposes, the top E ofthe cas` ing is preferably provided with a centralopen-- ing e', provided with a cover c2, which may.

is providedvwith legs n n, whereby it is sup ported from the surface upon which the said p casing rests. The said plate will be suping.

ported free from contactwith thel burner-'casing, and its margins will pr'e'ferablybe located 'upon the same level with the adjacentl floor of the car, the legs n nbeing arranged to rest uponthe bottom of the recessor pit within which the heating device islocated. By this the car-floor, and by being elevatedinits middle part at the Vsaine time alfords wample space beneath it for the burner and its cas-l The said plate. N is desirably provided` with a 4central opening n', within which is iitted a removable cover m2, said l opening it being preferably made larger thanth'e opening e of the casing E, so that the cover e2 of the latter may be removed through said opening n and access thereby had to the said -casing without removing the plate N; The

cover n2 is preferablyprovided with an open-` ing n3, filled by a plate n4, of mica or glass,

j whereby, in connection with the similar opening in the cover e2 beneath it, the burner-flame may be viewed from the interior of the car.

To facilitate the'free passage of smoke and products of. combustion from the exit-pipes M M, the latterare connected at their outer ends with horizontally-arranged pipes M M', placed parallel with the sides of the car and open at'v both ends. Said pipes M are provided with valves m m m on at their open ends, by meansof which the ends of the pipes which are in advance when the car is moving in either direction may beclosed and the ever direction the car `is moving; As preferably constructed, the valves fm 'nt' consist of horizontally-pivoted Hat disks, the support- 1 ing-pivots of which are connectedV with levers m2, located at the outside of the pipes.'` The free 'ends of said levers m2 belonging to the y valves 'm m of each pipe are preferably connected by a rod m3, and the said valves are arranged relatively to eachother in such` manner that when one valve is open 'the other is closed.` 'lhis'construction obviously enables both valves m and m to be properly turned by moving either'one of them or by moving the connecting-rod m3. I have shown in dotted lines at m4 a, handle applied to the rod m3, whereby the valves may be readily moved; but a preferable means for actuating r the said valves whereby they may all `be operated from the car-platforms is illust-rated in full lines and more clearly shown in Fig. 7.- Saiddevice consists of cross-bars M2 M2, rigidly connecting therods m3 m3 at opposite sides of the car, and rods or chains M3 M3, at#

tached to said .cross-bars and extended to points upon the car-platforms where they can be conveniently reached by thedriver or con" IIO they are connectedvwith chains -m5'm5, whichl pass over pulleysM4 M4 and are attached to,

vertically-sliding rods M5 M5, Figs. 2`and 7, extending upwardly through and sliding in the platform and provided with handles at their upper ends. By drawing upwardly upon the said rods at one or the other end of the car the valves on. ni may be shifted in an obvious manner.

The exit smoke-pipes'M' M are preferably located at the sides of the car exterior to the Wheels, and the main smoke-pipes M M are bent into spiral forni inA their parts which extend horizontally outward to said pipes M M', in order to facilitate the passage of t-he products of combustion through said pipes. This spiral construction of the smoke-pipes is advantageous, and is therefore herein claimed; but such construction is not essential to the successful working of other parts of the apparatus.

The oil-supply pipe D is shown in the drawings as provided with a regulating-valve D', Figs. 2 and 4, similar to that described and claimed in a prior application, Serial N 210,0l7, filed August 5, 1886, whereby the quantity of oil delivered to the burner may be accurately controlled. As herein vshown and preferably constructed, said valve is inclosed within .a box orcasing D2, provided with a lock, whereby access to the valve by unauthorized persons may be prevented.

The location of the heating device, made broad and flat, in the position shown-namely, in the middle of` the car-lioor-is of advantage as tending to produce-an equal diffusion of the heat throughout the car, the probable course of the warin-air currents within the car being approximately indicated by the arrows in Figs. 2 and I claim as my invention- 1.
